Configuration of multiple component carrier repetition transmissions

Abstract

A computer-readable storage medium stores instructions to configure a UE for multiple component carrier repetition transmissions in a 5G NR network, and to cause the UE to perform operations comprising decoding DCI received via a PDCCH. The DCI includes transport block (TB) information and scheduling information. The scheduling information indicating scheduled transmissions of multiple repetitions of a PDSCH TB using multiple component carriers. A TB size associated with the scheduled transmissions is determined using the TB information. The multiple repetitions of the PDSCH TB am decoded. The multiple repetitions are received from one or more base stations during the scheduled transmissions. PDSCH data is determined based on the multiple repetitions of the PDSCH TB and the TB size.
